Bulk-order quality control
Bamboo OEM Pre-Shipment Inspection Checklist
Use a pre-shipment inspection to compare one identified production lot with the approved drawing, specification and sample before release. The plan should state what is checked, how units are selected, how results are recorded, and who can approve shipment, rework or reinspection.
Freeze the inspection basis before the visit
A useful inspection starts with a controlled product definition. Put the purchase order, product or part number, drawing revision, material construction, finish reference, approved sample ID, packaging artwork and accepted deviations in one review pack. If the order changed after sample approval, identify the affected checks and approve the new revision before inspection.
If the reference is not yet controlled, first use the bamboo product sample approval checklist. For drawing-led parts, settle datum, tolerances, holes, slots, grain, visible faces and edge requirements with the CNC and DFM checklist.
Define the inspection plan
Lot and timing
Identify the production lot, quantity, SKU or revision mix, location and inspection stage. State how much must be complete and packed before the inspection starts, and whether any tests need conditioned samples or advance preparation.
Unit selection
State how cartons, pallets and units will be selected across the lot. If the buyer uses a statistical sampling plan, name the agreed standard or table, inspection level, sample size and acceptance limits. Do not apply one universal AQL to every bamboo product or defect.
Defect classification
Define critical, major and minor defects for the actual product and intended use. Tie each example to a drawing, specification, approved appearance range or packaging requirement. Natural bamboo variation still needs an agreed boundary when appearance matters.
Method and evidence
Name the instrument, gauge, fixture, test setup, lighting or viewing condition, measurement locations and units. Specify the photo, measured result, count, label or document evidence needed in the report.
Disposition
State who may release, hold, rework, sort, accept a deviation or require reinspection. A failed item should identify the requirement, observed result, affected quantity and proposed corrective action.
Inspector scope
Confirm whether HTR, the buyer or an arranged third party performs each check. Product validation, laboratory testing and destination compliance remain separate unless the written scope expressly includes them.
Eight pre-shipment inspection checks
| Check | What to compare | Evidence to retain |
|---|---|---|
| 1. Lot identity and quantity | PO, SKU, drawing or specification revision, lot or batch labels, produced quantity, packed quantity and incomplete or segregated stock | Lot summary, label photos and quantity record |
| 2. Material and construction | Bamboo format, layer or grain direction, thickness, backing, visible faces and edges, adhesive or assembly details that form part of the order | Reference match, section or edge photos, measured values and document identifiers |
| 3. Dimensions | Critical dimensions and tolerances from the controlled drawing, using the agreed datum and measurement conditions | Instrument or gauge, measurement locations, results by sampled unit and failures |
| 4. Appearance and finish | Colour or approved range, grain, coating, sheen, texture, sanding, visible edge, logo and workmanship limits | Photos under the agreed viewing condition, defect counts and sample comparison |
| 5. Fit and function | Assembly, hardware, mating part, movement, stability, handling or buyer-defined functional check | Fixture or method, result, video or photos where useful, and any excluded end-use test |
| 6. Packaging and labels | Unit protection, moisture-control arrangement where specified, pack count, barcode, artwork revision, carton marks, accessories and pallet pattern | Open-carton and closed-carton photos, pack count, dimensions, weights and pallet record |
| 7. Order documents | Inspection report, packing list inputs, certificate or test-report scope where applicable, labels and shipment documents assigned to the supplier | Document checklist with revision, issuer, product scope and open items |
| 8. Release decision | All results, deviations, rework, sorting, replacement, reinspection and written buyer decisions | Signed or traceable release, hold or rejection record |
Write product-specific defect examples
Terms such as “scratch,” “colour difference” or “dimension out” are too vague on their own. For each relevant defect, state the surface or feature, limit, measurement or reference, allowed location or quantity, and severity. A cosmetic mark on an unseen packaging insert is different from a splinter on a handled edge or a wrong hole position in a mating component.
- Critical: define conditions that create an unacceptable safety, legal or essential identity risk for this product.
- Major: define failures likely to prevent intended assembly, sale or use, or to depart materially from the approved specification.
- Minor: define limited workmanship or appearance differences that do not meet the recorded standard but are less likely to impair intended use.
These descriptions are planning categories. Their final meaning, sampling and limits must come from the buyer-approved inspection plan and applicable requirements.

Close failures before shipment
- Identify the nonconformity. Cite the controlled requirement and record the observed result and affected quantity.
- Contain the lot. Separate affected units and prevent loading while the decision is open.
- Agree the action. Rework, sort, replace, accept a named deviation or reject according to written authority.
- Verify the action. Record the reinspection scope and result. Do not treat a promise to fix as a passed reinspection.
- Release the matching shipment. Link the final inspection status to the packing list, carton or pallet identity and the agreed shipping terms.
For packaging risk, use the bamboo packing and shipping guide. Confirm order-specific certification and report scope on the certifications and compliance page.
Pre-shipment inspection questions
Does HTR use one AQL for every order?
No universal plan is appropriate for every panel, component, knitting tool, finished product or defect. The quotation or inspection brief should identify the buyer-agreed sampling and acceptance method.
Can an approved sample replace production inspection?
No. The approved sample and drawing provide the comparison basis. Production inspection checks the selected lot against that basis and the agreed acceptance plan.
Can a third party inspect the order?
Third-party inspection can be arranged when agreed before shipment. The buyer should provide or approve the scope, timing, access, sampling, criteria, report format and decision authority.
Does a passed inspection guarantee every unit or the final consumer product?
An inspection reports the defined checks on the identified lot and selected units. It does not replace product validation, laboratory testing, legal compliance or checks outside the written scope.
Send an inspection-ready order brief
Share the product, PO or lot, approved drawing and sample, critical dimensions, appearance and functional criteria, sampling plan, defect definitions, packing, documents, destination and decision owner. HTR can identify missing inputs and confirm what can be checked by HTR or an arranged third party before shipment.
